To ThreadStarter,
Thanks for sharing this information.
It is a very good visualisation aid for all.
I will add in the photo at the Night Photography section for sharing at a later stage.
It is true that it is very hard to capture stars or star trails in Singapore due to Light Pollution.
So far, some of my friends had tried shooting from Pulau Ubin but it is still quite bright.
I think so far my best stars shooting experience is in Port Campbell in Melbourne, Australia.
Just to share some of my recent work with you.
To other more senior members,
Great knowledge comes from knowing when to answer and when not to answer.
Please try to refrain if you do not have any thing to value add in this discussion.
I have delete those OT and inappropriate comment.
